Audio rendering of mathematical expressions has accessibility benefits for people with visual impairment. Seeking a systematic way to measure participants' perception of the rendered formulae with audio cues, we investigate the design of performance metrics to capture the distance between reference and perceived math expressions. We propose EAR-Math, a(More)
Mobile technologies provide radical opportunities in the domain of Assistive Technologies (AT) for persons with disabilities and the elderly by facilitating them to access multimedia content and improve their social interaction. The search for mobile AT applications that meet specific user needs is not an easy task for the disabled users, their(More)
We introduce and compare three approaches to calculate structure-and content-based performance metrics for user-based evaluation of math audio rendering systems: Syntax Tree alignment, Baseline Structure Tree alignment, and MathML Tree Edit Distance. While the first two require " manual " tree transformation and alignment of the mathematical expressions,(More)
